I had two implants in 2007. Both drilled and fixed in the same day, but no crowns fitted until gums and bone fully healed 3 months later. Still as good as new.
I often hear adverts on the radio for TCD Smile in a day full dental implants in one day. I don’t need it but. i looked up as curious. Full top and bottom sets for £15,950. The thought of all those teeth coming out and the implants drilled in one day is mind boggling...
